Yup, you should see the horrendous dirty mess that is my Pogonomyrmex subnitidus mini-hearth. I can't see a thing. I'm getting some flat stuff (e.g. Fallen Fortress) just for them.
And I agree - I like the Fallen Fortress and Labyrinth design a LOT. Great visibility. Can easily find the queen. etc.
